Fill each bag with about 10 ml of solution using a 10 ml graduated pipette. The student placed the tube in a solution and the mass of the tube and its contents increased to 60 grams. Dialysis tubing must be soaked in water before you will be able to open it up to create the dialysis bag.
Fill the dialysis bags with the solutions listed in the Dialysis tubing bags column of the table in the following way. The sealed dialysis bag is placed in a container of a different solution and molecules small enough to pass through the tubing move into or out of the dialysis bag in the direction of decreasing concentration. The tube and its contents had a mass of 55 grams.
Follow these directions for this experiment. Larger molecules including proteins DNA or polysaccharides. What is the climate of central africa.
